Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative relationship between the components in a certain posture (as shown in the accompanying drawings). When the positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly. Furthermore, the terms "installed", "disposed", "provided", "connected", "connected", "socketed" are to be interpreted broadly. For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediary; internal connectivity. Those of ordinary skill in the art can und...

Abstract

The invention discloses a fixing method for a wedge-shaped steel tenon at movable end of an assembled steel support. The fixing method comprises the following steps that S1, pre-applied force is applied to the steel support, a steel support steel pipe and the movable end are expanded, the stretching length is measured, and the length of a vacant space between two steel beams stretched out of the movable end is determined; S2, according to the length of the vacant space, the combination and number of uniform-section steel tenons are calculated and determined, and after the uniform-section steeltenons are filled, the vacant space with a certain length is reserved; and S3, a pair of wedge-shaped steel tenons are plugged into the reserved vacant space with the certain length, then the wedge-shaped steel tenons are extruded through a fastening device, and then the uniform-section steel tenons are pressed. According to the fixing method, the erection time of the steel support is saved, thetechnical content of steel support erection is increased, meanwhile, an existing wedge-shaped tenon hammering and plugging method process can be effectively improved, the risk that the wedge-shaped steel tenons are popped out is eliminated, and the good future achievement transformation prospect is achieved; and the wedge-shaped steel tenon can be directly manufactured into a product and widely applied to deep foundation pit steel support construction, especially a long and narrow foundation pit of a subway.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for fixing a wedge-shaped steel falcon at the active end of an assembled steel support. Background technique [0002] There was a problem with steel braced construction. The deep foundation pit support structure consists of two parts, the enclosure structure system consists of bored piles, underground diaphragm walls, etc., and the support system consists of internal supports, anchor rods, and purlins. They are important measures to ensure the stability of the wall of the vertical excavation foundation pit and the deformation of the surrounding environment to meet the requirements of the code. In order to give full play to the function of the enclosure structure, the erection of internal supports can increase the rigidity and bearing capacity of the enclosure structure. There are two types of internal support: concrete support and steel support. Concrete sup...
